Throw your stuff on the back of your bike and go. The Topeak Explorer tubular rack is a strong, durable rear rack that's compatible with disc brake mounts, so it's perfect for use while bike touring, commuting, or just hauling around some extra stuff.

MTX QuickTrack mounting system works with traditional panniers and Topeak MTX trunk bags

MTX system allows for quick attachment and removal of bags, perfect for commuting

I needed a rack on my commuter with disc brakes. I had plenty of other racks, but none worked with a disc brake set up. This looked like it fit the bill. It worked just fine. Installation is like any other rack. It comes with all the screws you will need.

I use this to carry what I need at work for the day (change of clothes, lunch, etc). I think Topeak's pannier bag/rack combo is the best. The slide in system makes it very secure. If you stop somewhere, you can just slide the bag off the rack and take it with you. Excellent. I also have the smaller seat post rack and the plastic rail on that one makes a better connection with the bag (less vibration), but this one holds a lot more.
